Texas's 3rd House of Representatives district

District 3 is a district in the Texas House of Representatives. It was created in the 3rd legislature (1849–1851).

The district has been represented by Republican Cecil Bell Jr. since January 8, 2013, upon his initial election to the Texas House.

As a result of redistricting after the 2020 Federal census, from the 2022 elections the district encompasses southwestern, and portions of southeastern and south central, Montgomery County. Major cities in the district include all of Magnolia and Stagecoach, and a portion of Conroe.
